To alz'who'me'zfmag concern: v 1

Be it known that l, Bonn er W; Soo'r'r, a citlzen of the United States of America, re-

siding in Babylon, in the county of Suffolk,

in the State of New York, have invented certa n new, and useful Improvements in Timingfionnections for Dial and Cylinder Knitting Machines, of which the following is a specification.

My invention relates more particularly'to knitting machines of that class in which cylinders and dials both carrying knitting instruments are used, and in which it is im 1 portant to secure a desired cooperatlve rela tion of the, instruments in the dial to the instruments in the cylinder.

My invention provides means whereby the relative positions of the knitting instruments in the dial and cylinder may be readily adjusted. And first I will describe how this adjustment may be efiected by hand inconnection with the invention which forms the subject of my Patent 1,356,092, dated October 19, 1920. In the machine illustrated and described in that patent the dial is carried by a hinged frame, so that the dial may be lifted from its working position in relaitor insuring the proper relation of the knitting instruments in the dial to the instruments in the cylinder on the returnof the dial to its working position, and that was accomplished throughthe use of a two-part clutch in the gearing which operated' the cylinder and dial, one part oi the clutch being providedwith a clutch to cooperate with" a pin or pair of pins on the other part.

111 the accompanying drawings- Fig. 1 is a vertical section, showing one part of the mentioned clutch, but embracing means for carrying out my present invention;

"git-udinal bore in the clutch part 51.

Fig. 2 is a sectional view on the line 2-2,

tarlly ad usted, the screw being in that case been adjusted,

when freed from the hold of the of the clutch are marked and 51, interposedrinthe train of gearing between the needle cylinder 5260 and the dial it of the knitting machine or my above mentioned patent, As seen inn 6, this train of gearing: includes. abevel wheei 810, which drives the needle cylinder 260 turning within the stationary cams C on the bed plate, and on this shaft 32' is another b el gear 38 engaging-a bevel pinion 34011 a sp', lle 35, which carries its upper end a pinion 36. I The train of gearingis continued through pinions 37,38 and 39, in box 4-2, spindle 40 in bearing ell, to'clutch parts 50 and 51. The

upper clutch part 51 is mounted on spindle '3 n bearingplate 2 and carries a bevel pinion 13 gearing into a bevel pinion l i on horizontal shaft 45 in bracketl, which also carries the be ing plate 2. This shaft 45 has bevel pinionI i-h meshing into bevel plnlon 4-7 on the upper 'end'of spindle 18,

whichcarries'the dial 4t. The bracket 1 also carries the usual latch ringoeO. These parts are as described in my abhve mentioned patent. P i Y I On the lower face of apin 5Q Whichco-acts with a part Ii secure adjustment oi'the relation oi? th knitting instrumentsoi the dial to those of the cylinderby the simpleexpedient oi? Hittlithe clutch part '51 is pin on the iiirccording to my piicsr-int invention ing this clutch pin adjustable about the ofthe clutch] For this purpose, instead oi mounting this pin 52 fixedly on or making it part of the clutchjpart 51,1 mount it eccentrically on the end or a stud 1-0 set'in a 1011 The stud may be'heldin position longitudinally of the bore in the clutch part bya lateral set'screw 11 threaded into a tapped .holein theclutch part 51, and with its inner end entering a reducedpart of the stud. 'The same set. screw. may be used tosecure the studin the position to which it may be ropart.

the proper correction can be, made byloosening the screw 11 and with thumb upon the knurled portion 12, the stud 10 can be turned slightly with the result that the eccentrically mounted pi 52 is caused to traverseto a slight extent, and by thus changing the relations of the two clutch parts to each other, to that extent, the instruments in the dial and cylinder are brought into .thedesired relation to each other.

In certain casesl may make this adjust ment automatic. For example, in Figs. ,3,

l: and 5 l have shown means for automatically adjusting the pin 52 which-is carried by the clutch part 55, and in Fig. 3 I have shown the other clutch part 56as mounted in a special way upon the upper end of-the.

spindle. In this connection, the stud 20,

which carries the clutch pin 52 ecce ntrically, mounted at its lower end, has threaded mto its side a pin 22 which )asses freel throu iha horizontal slot 23 in the wall of the clutch part;

tothe pin 22 by the inclined slot 2%, and the clutch pin 52 adjusted accordingly to cause a change of position of thekmttmg machine dial rotarily in relation to the cylinder.

The movement of the sleeve 25 may be effected automatically from the pattern drum of the machine, through the medium of a lever 27 pivoted at 28and acting at one end in an annulargroove 30' in the r1ng25 and acted on at the other end by a thrust bar 29, e

such as used in the well known Scott and l Villiams machines.

Such an automatic mechanism as, I have described is especially useful in effecting a change of relatio of dial to, cylinder rotarily, when that change has to be made, at certain intervals in lrnittin and not merely to get. the instruments into permanent. relationship. Thus in certain forms of knitting machines. especially for producing rib.- bed fabric, it is desirable that means be provided for shogging the needles of one carrier, usually those needles. carried by the dial. so that said needles may be caused to ply between pairs of needles immediately adjacent to those between which they work to produce the ordinary ribbed fabric. This is done at times to produce ornamental courses of shogged stitches and at otherto be applied'to a separate machine for knitting the foot of astocking- Reference may be had to patent to W; H. Childrey,

No. 1,306,523, June10, 1919 as an illustration of the practice in this connection. In the said patent toChildrey, provision is made for changingv the relative positions of the cylinder and dial needles by imparting to the dial an intermittent movement always in the same direction, and while this 11'- rangementhas functioned well in practice, it is desirable'in certain forms of machines that this shiogging or racking should take place first i one direction and then in the opposite direction for the space of one needle.

The, construction of automatic adjustment which l'have above described in connection with Figs. 8, i and 5 is useful for thispurpose. Then it is desired to change the dial needles from oneknitting'positionto the-other, the said dial needles are withdrawnintothedial so that the hooksof all of them, are inside the ring of cylinder needles. VVhenin this position the thrust bar 2:) is raised to-depress the forward end tially turned on} its axis and the clutchpi 52 -w1l1 have lts posit on so far changed as to turn the dial a distanceequal'to one needle space. Thereupon knitting is re suined with, the dialneedles in the new position. until it is desired to return them to their first position. Then the pattern drum acts. to let the thrust bar 29. return and a spring-3l causes the sleeve to rise andthe parts are returned to the first position.

I claim as my invention- 1. A knitting machine having cylinder and dial, both carrying knitting instruments in combination with connecting gearing for driving. the two and including a clutch and means foradjusting the clutch, to change the relation of the dial tothe cylinder rotarily.

2. 2r knitting machine having cylinder and dial, both carrying knitting instru:v ments, in. con' bination with connecting gearing for driving the two and. including a clutch, one part of said clutch being proi vided with; a rotarily adjustable stub carry ing a clutch pin eccentrically mounted thereon.

In testimony whereof I have signedmy name to this specification. I
